FASTENING FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 316,822, dated April 28, 1885.

Application filed July 10, 1384. (No model.)

and B the lower rail of the top sash, through which are the holes a a and b b, made to reg- To aZZ whom it may concern.-

Be it known that I, WILHELM POHLMANN, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Sash-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to window-sash fastenings, the object being to fasten the upper and lower sash together by bolts passing through the upper rail of the lower sash and into the lower rail of the upper sash, and with mechanism so arranged that the bolts are widely separated, to the end that the sash are more firmly held than with the ordinary fastenings that secure the sash only at one point. A further object is to connect the bolts by means of levers, so that they are simultaneously operated by a central knob. A further object is to provide a jointed knob by means of which, when the sash are bolted, the free end of the knob will turn down by its own gravity and lock the device. A further object is to provide a set-screw so arranged that when the sash. is unbolted the apparatus may be locked or secured, so that when the sash are moved the upper sash will not be marred by the bolt left protruding from the lower sash.

With these objects in view my invention consists in certain features of construction and in combinationof parts,hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view from the lower side of my improved sash-fastener in fposition, with the sash unlocked. Fig. 2 is the same view, but with the sash locked. Fig. 3 is a longitudinal section through the center of the central post and sliding block in the position these parts assume when the sash is unlocked. Fig. 4 is a section of the center post and sliding block and a side view in elevation of the knob with the parts in position for locking the sash. Fig. 5 is a view in perspective of one of the levers. Fig. 6 is a view in perspective of the shifting-block G.

A represents the top rail of the lower sash,

ister in pairs, as shown.

C are bolts that slide through the respective holes a b, and have slotted heads that embrace, respectively, the end (1 of the levers D, and

I have a pin, a, that passes through the elongated The block has a transverse mortise, g, near the inner end, in which the ends (2" of the levers D enter and overlap each other, and the 1 part F has slot-s, f, on either side, through which the levers pass before reaching the sliding block. The block G has a thumbscrew, that passes laterally through the block and at right angles to and through the center of the mortise, and passes through the elongated hole d of the levers. The shank of the thumb-screw passes out through the slot f on the top side of the part F. When the thumbscrew is screwed in, it presses against theinner side of the part F and holds the block from sliding. The outer end of the block G has a slot, 9', at right angles to the mortise, in which is pivoted on the pin 9 the tenon h of the knob H. This knob has ahollow cylindrical part, h, that, when the knob and block are depressed, closes over the end of the part F and hides the short slot f 2 on the lower side of the part F.

The device, as aforesaid, is attached to the face of the rail A, and consequently the part F extends forward horizontally,and is usually at such distance from the floor that only the this position the set-screw should be tight ened,so that the bolts are held back in the rail A. Without this precaution the upper sash is liable to beIinjured. Forlinstance,' suppose the lower sash has been raised, and in adjusting the curtain or from other cause the levers have been moved so that the bolt ends protrude from the rail A, these protruding ends will mar and injure the upper sash when the lower sash is drawn down.

WVhen it 'is:desired;to lock the sash,the setscrew is loosened and the knob is'drawn forward, as shown in Fig. 2, by means of which and the connections already described the bolts are thrust into the holes in the railB, thus securing or looking thesash. The knob, after being: drawnout and left free, will fall by its own gravity to the position shown in Fig. 4, the tenon h meantime entering into the slot f of the part F, by means of which the parts are secured in-the position that locks the sash and the levers cannot be movedto unlock the sash without first raising up the knobs to ahorizontal position. The levers D are of considerable length, so that the bolts 0 operate at widely-separated points,and'the sash by this means are held from rocking and are much firmer than with the ordinary sash-locks that operate only at one point.

Vhat I claim is- 1. In a sash-lock, the combination, with twolevers centrally pivoted to one of the sashes and provided on their outer ends with bolts, of a knob pivotally attached to the inner or adjacent ends of both levers, substantially as set forth.

2. In a sash-lock, the combination, with the socket or boss secured to a window-sash, two levers centrally pivoted on opposite sides of said boss, and bolts pivoted to the outer ends of said levers, ofa movable block located withinlthe sleeve orlboss and pivotally connecting the inner ends of the levers, and a knob secured to the block.

3. In a sash-lock, the combination, with the slotted socket or boss secured to awindowsash, two pivoted levers located in the same horizontal plane on opposite sides of the socket, and bolts pivoted to the outer ends of both levers, of a movable block located within the socket and loosely connecting the adjacent ends of the levers, a knob connected to the block for operating the levers, and a set-screw for lockingthelevers, substantially as set forth.

4. The combination, withIthe socket or boss, the levers, bolts pivoted to the levers, and the block connecting theinner ends of said levers, of the knob pivotally secured] to the block, andjlhaving the cylindrical band adapted to fit around the outer end of the socket or boss, substantially as set forth.

In testimony whereof I sign'this specification, in the presence of two witnesses, this 26th day of June, 1884.
